Grape plant named &#39;Arraten&#39;

ABSTRACT

A new distinct variety of grapevine named ARRATEN abundantly forms attractive medium-to-large seedless berries having a 90% fire red skin coloration with 10% creamy yellow, in medium-to-large clusters. The fruit displays a sweet crisp flavor and is film in texture. The fruit commonly is ready for harvesting during the end of June in San Joaquin Valley of Central California, U.S.A., and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.

CLASSIFICATION

The present invention relates to a new Vitis vinifera Grapevine.

VARIETY DENOMINATION

The new Grapevine has the varietal denomination ‘ARRATEN’.

BACKGROUND OF THE INVENTION

A breeding program was initiated during the late 90's near Bakersfield in San Joaquin Valley of Central California. In 2000, during this breeding program, a new variety of Vitis vinifera was created by deliberate cross breeding of two parent plants by emasculation of the pollen bearing organ of the male and introducing pollen from another male origin. The female parent of the new variety was the GAR4 which is a dark red, elongated meaty grape variety with a very small seed trace and low sugar content (non-patented in the United States). The male parent (i.e. the pollen parent) of the new variety was GZR2 which is an oval shaped, meaty, juicy and sterile grape variety (non-patented in the United States).

The parentage of the new variety can be summarized as follows:

An artificial pollination was created, and the result was an embryo which possessed unique genetic qualities. The rudiments resulting from the above pollination were embryo rescued.

In 2001 the plant was then transplanted to Bakersfield in San Joaquin Valley of Central California.

It was found that the new grapevine of the present invention possesses the following combination of characteristics:

(a) Forms attractive medium-to-large seedless berries having a 90% fire red skin coloration with 10% creamy yellow; in medium-to-large clusters which display a slight Muscat flavor;

(b) Commonly bears fruit during the end of June in the San Joaquin Valley of Central California, U.S.A.; and

(c) Bears fruit that is firm and is well amenable for storage, handling, and shipping.

The new variety during observation to date has displayed no visible disease, and has displayed an ability to well resist cold, drought, heat; but sensitive to direct exposure to sun and wind. The fruit of the new variety has been found to display excellent handling and shipping qualities combined with desirable dessert eating qualities.

The new variety of the present invention has been found to undergo asexual propagation beginning in 2004 near Bakersfield in the San Joaquin Valley of Central California, U.S.A. by grafting on mature ‘Thompson Seedless’ rootstock (non-patented in the United States). Such asexual propagation has been conducted thereafter in successive years through 2007, and has shown that the characteristics of the new variety are strictly transmissible from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true to type manner. The age of the plant in the drawings is five years old and the variety was created in 2000.

SUMMARY OF INVENTION

The new variety ARRATEN is a large, elongated, fire red, seedless table grape and is very weak at the attachment to the stem large production, e.g., about 40 to 50 bunches per vine, and an average of about one to two bunches per shoot.

Asexual reproduction by micro propagation of the new variety as performed near Bakersfield, Calif., U.S.A., at Arvin, Calif. Ranch 33 which shows that the forgoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic illustration shows typical specimens of vegetative growth of five year old specimens of the new variety, in color as nearly true as it is reasonably possible to make in a color illustration of this character. Colors in the photograph may differ from the color values cited in the detailed botanical description below, which accurately describes the colors of the new Grapevine.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is the R.H.S. Colour Chart of The Royal Horticultural Society. The description is based on the observation of plants growing on ‘Thompson Seedless’ rootstock outdoors near San Joaquin Valley of Central California, U.S.A.

-   The ARRATEN variety has not been observed under all possible     environmental conditions to date. Accordingly, it is possible that     the phenotypic expression may vary somewhat with changes in light     intensity and duration, cultural practices, and other environmental     conditions.
